Power Meters FAQ's



All Ophir RS232-speaking instruments can communicate with a Linux machine. There is no dependence on which operating system is being used on the other side – it’s a simple command and response protocol.

Programmers wanting to use commands via RS232 to control and collect data from an Ophir instrument need to refer to Appendix A in the “StarCom” User Manual - ‘Guide to Programmers’ section. This can be downloaded from the “Download – Manuals” section of our website, https://www.ophiropt.com/laser-measurement-instruments/laser-power-energy-meters/services/manuals

We have recently developed a package that enables USB communication with our meters from a Linux machine. It is now in beta-testing and has been released to several selected users. If you'd like to get this package, please contact us.


System Integrators will need the following components:

  • OphirLMMeasurement COM Object.pdf lists and describes the methods and events available for configuring, controlling and uploading measurements from Ophir devices.
  • OphirLMMeasurement.dll. COM object component developed and supplied by Ophir for communication with the Juno, Nova-II, Pulsar, Vega, StarBright and StarLite devices. The COM object is registered when the application is installed.
  • OphirLMMeasurement COM Object.pdf describes how to register it on another PC where the Ophir application has not been installed.
  • Standard micro-B USB cable (P/N 7E01279) for use with the StarBright device (included).
  • Ophir provides example projects of COM Object clients in VC#, VB.NET and LabVIEW. These are found in the Automation Examples subdirectory of our StarLab PC Application.
  • For direct control of the device, refer to User Commands.

In order to get started, install the latest version of StarLab on your PC. The COM Object registration is included in the StarLab installation process.

  • Download Nova VIs (468 KB) and run it.
  • This will run the WinZip Self-Extractor and default to unzip the Nova VI's to "C:/Program Files/National Instruments/LabVIEW 6.1/instr.lib". To select a different target folder, press the "Browse" button.
  • Press the "Unzip" button to complete the self-extraction process.
  • Press "Close" to close the session.

To install StarCom on your PC please do the following:

  • Please uninstall previous version before installation.
  • Download StarCom V3.20 (3.75 MB) - [32-bit].
  • Run the file and follow the on-screen instructions.
  • After installation is completed, you can Run the StarCom Application from your computer Desktop.
